Recent extensions to DSD theory and modeling argue that in addition to the total
shock-front curvature, the intrinsic front propagation law can depend on other
variables. Here we outline this recent work and present results of high-resolution
numerical simulations of 2D detonation that verify the theory on some points,
but disagree with it on others. We discuss how these results impact the analysis
of PBX 9502 shock curvature data.
I-INTRODUCTION
The benefits of using insensitive high explo-
sives (IHE) like PBX 9502 (9502) have been well
documented [1]. These desirable features come
at a price. The reaction zone is longer for IHEs,
thus making them more nonideal. In real world
applications, this translates into significant per-
formance problems, such as problems with deto-
nation wave spreading. The speed of detonation
propagation is affected over large regions. To be
